Think here's what he tried to convey.. HCO2H could be oxidised by the oxidants that oxidise aldehydes (in this case, Fehling's), it's not that HCO2H can be oxidised to form an aldehyde, but I think what the question stated was that HCO2H can be oxidised the same way aldehydes are oxidised.. So essentially the question said that HCO2H, similar to aldehydes, can be oxidised by Fehling's or Tollen's, etc.. Question was pretty weird tho, one of my friends also answered another carboxylic acid as well..

Was that one D? Zn, (either one of NaF or KCl), and SiCl4?
C was Zn, (either one of NaF or KCl), and HCl..
Was SiCl4 hydrolysed to form HCl (and SiO2), where HCl conducts electricity in aqueous? So answer is D, right? I have a bit of doubt in this one, but my gut says D..
